To all whom it mayconcern:

Be it known that I, HENRY L. Fnnms, a citizen of the United States,residing at Harvard, in -the county of McHenry and State of Illinois,have invented new and useful Improvements in Fasteners for Doors, ofwhich the following is a specification.

- My invention relates to certain new and useful improvements infasteners for doors, and is fully described and explained in the,specification and shown in the accompanying drawings, in which:

Figure 1 is a perspective, showing the door arrangement to which my lockis applied. Fig. 2 is a horizontal section on the line 3 of Fig. 1, andFig. 3 is a vertical section on the line? of Fig. 2.

Referring to the drawings, 5 is a track above the door-opening, and 6 isa track at rightangles thereto, and secured to the wall of the building.The door is supported by two hangers 7 and 8, respectively mounted inthe two tracks 5 and 6, and therefore at right-angles to each other. 9is a door, which, when opened, swings back under neath the track 6, thehanger 8 moving in said track backward from the door-openmg, and thehanger 7 movingalong the track 5 until the door is parallel to andbeneath the track 6.

It is obvious that a sliding door of this kind requires a different lookfrom those commonly in use, for the reason that while the ordinarysliding door is usually locked at its front end, that is, at the endwhich is forward in the closing movement of the door, such a lock iswholly unsatisfactory on a door of this kind. If the front end of thepresent door be locked, the rear end can swing back a. considerabledistance, owing to the necessary lost motion of the doorlock, and itwill be blown partiall open by wind. My present look, there ore, isapplied to the rear end of the door and is designed to draw the sameforcibly forward in a direction at right-angles to the plane of thedoor.

For this purpose the door is perforated at 10. Into the perforation isset a metal cup 11, in which is supported a yoke 12, normallyspring-pressed backward by a spring 13, the backward movement beinglimited by a pin 14. The back end of the yoke is inclosed by a cap 15,held in place by a bolt 16. The arrangement is such that theSpecification of Letters Patent. Application filed December as, me.Serial No. 1aa,s11.

tion of the line connecting the yoke wlth the pivot of the lever, or, inother words, past the dead center. The lever is thus of the self-lockingkind. Its locking m'ovement toward the door-jam-b is limited byengagement with an ear 21, which enters the groove 22 in the lever 19and which is provlded with a perforation 23, through which an ordinarypadlock may be passed to lock the lever in closed position.

The structure is thus one which holds the door firmly closed, and with ayielding tension exerted at right-angles to the plane of the door. ThlSnot only prevents the door from being opened to an extent sufiicient toafford access to the structure, but it holds the back end of the door,which would otherwise be free to move inward, firmly against the door-jamb, and affords, for this par.- ticular type of door, a thoroughlysatisfactory lock.

I' realize that considerable variation is possible in the detailsof-this construction without departing from the spirit of m invention;therefore I do not intend to imit myself to the specific form hereinshown and described except .as pointed out in the following claims, inwhich it is my intention to claim all the novelty inherent in theconstruction as broadly as is permitted by the state of the art.

What I claim as new and desire to secure by Letters Patent is 1. Lockingmeans of the character described comprising a door having a perforationtherein, a bearing seated in said perforation, a spring-equipped yokemovably mounted in said bearing and having its inner end lyingsubstantially in the plane of the door, a cap closing the outer end ofthe aperture through the door, a hook supported from the door j amb andadapted to engage said yoke, and means to draw the hook outma am wardlyfrom the plane of the door to draw from the door jamb and adapted toenga e and lock the door against the door jamb. said yoke, a leverivotally mounted on t e 2.
